JSON Parameters

I'm trying to make an scenario at a web application that uses a lot of json, my first challenge was to make a list of parameters for codes, an then use the selected code an pass it to the next step, however I can't do that. Can you help me pls?

Step 7:I try to use the variable "hotel"{"hotelCode":$Var(hotel),"languageCode":"es","posCode":"CRMX"}

and finally I run the test...

at the logs I found the same: {"hotelCode":$Var(hotel),"languageCode":"es","posCode":"CRMX"} and I expected {"hotelCode":"ECA","languageCode":"es","posCode":"CRMX"} or {"hotelCode":"FIN","languageCode":"es","posCode":"CRMX"}
